The first driven disk 7 is fixedly connected to the side close to the second driven disk 9 with a driving block 8. The second driven disk 9 is fixedly connected with a first driven block 10 and a second driven block 12 that cooperate with the driving block 8. The first driven disk 7 drives the first driven block 10 or the second driven block 12 to move through the driving block 8, and then drives the second driven disk 9 to rotate. Support rods are connected between the first rotating shaft 13 and the first foot support 2, and between the second rotating shaft 14 and the second foot support 3. When the first driven disk 7 and the second driven disk 9 rotate, they will drive the first rotating shaft 13 and the second rotating shaft 14 to move, and push the first foot support 2 and the second foot support 3 to move through the support rod, thereby driving the user's legs to move.

[0026] In some specific embodiments, the driving block 8, the first driven block 10 and the second driven block 12 are all in the shape of a triangular prism with an arc surface, and the arc surface is arranged on the driving block 8, the first driven block 10 and the second driven block 12 at a position away from the central axis of the first driven disk 7 and the second driven disk 9. The angles between the two side surfaces connected on both sides of the arc surface on the driving block 8, the first driven block 10 and the second driven block 12 are both 15°, and the angle between the first driven block 10 and the second driven block 12 is 195°. Initially, one side of the driving block 8 is in contact with the first driven block 10. When the driving block 8 rotates 180° along the axis of the first driven disk 7, the other side of the driving block 8 will be in contact with the second driven block 12, so that the first driven disk 7 and the second driven disk 9 have two matching states. The first state is: the first driven disk 7 rotates counterclockwise to drive the driving block 8 to move, and the driving block 8 drives the second The driven block 12 moves, thereby driving the second driven disk 9 to rotate. At this time, the first rotating shaft 13 and the second rotating shaft 14 are symmetrically arranged on both sides of the first driven disk 7 and the second driven disk 9, thereby driving the first foot support 2 and the second foot support 3 to move synchronously. The second state is: the clockwise rotation of the first driven disk 7 will drive the driving block 8 to move, and the driving block 8 drives the first driven block 10 to move, thereby driving the second driven disk 9 to rotate. At this time, the first rotating shaft 13 and the second rotating shaft 14 are respectively located at diagonal positions on both sides of the first driven disk 7 and the second driven disk 9. At this time, the first foot support 2 and the second foot support 3 will move asynchronously one after the other, thereby driving the user's legs to move one after the other, respectively, and controlling the speed of the motor 4 so that its effect is similar to walking and massage. It should be noted that the speed of the motor 4 needs to be adjusted within a certain range as needed to avoid causing harm to the user.

[0027] In some specific embodiments, in order to drive the first driven disk 7, the driving assembly includes a motor 4 fixedly connected to the bottom of the nursing chair body 1, and the output end of the motor 4 is coaxially fixedly connected to the active disk 5. The first driven disk 7 and the second driven disk 9 coincide with the central axis of the active disk 5, and the first rotating shaft 13 is eccentrically connected to the active disk 5. The motor 4 drives the first rotating shaft 13 to move through the active disk 5, thereby driving the first driven disk 7 to rotate.

[0028] In some specific embodiments, in order to ensure the use effect, the support rod includes a spring telescopic rod 6. There are two groups of spring telescopic rods 6, which are respectively arranged between the first rotating shaft 13 and the first foot support 2 and between the second rotating shaft 14 and the second foot support 3. They are rotatably connected to the first rotating shaft 13 and the second rotating shaft 14, and are movably hinged to the first foot support 2 and the second foot support 3. The spring telescopic rod 6 can push the first foot support 2 and the second foot support 3 to move forward and backward. At the same time, the elasticity of the spring telescopic rod 6 itself can play a buffering role to avoid damage to the joints during movement.

[0029] In order to facilitate the understanding of the embodiments of the present invention by those skilled in the art, the working principle of the embodiments of the present invention will be described in combination with specific application scenarios: when in use, the user sits on the nursing chair body 1, and the two calves are placed on the first footrest 2 and the second footrest 3 respectively. The driving motor 4 rotates clockwise to drive the driving block 8 to move, and the driving block 8 drives the second driven block 12 to move, thereby driving the second driven disk 9 to rotate. At this time, the first rotating shaft 13 and the second rotating shaft 14 are symmetrically arranged on both sides of the first driven disk 7 and the second driven disk 9. The first rotating shaft 13 and the second rotating shaft 14 drive the spring telescopic rod 6 to move, and the first footrest 2 and the second footrest 3 will move synchronously, thereby driving the user's legs to swing back and forth synchronously, thereby achieving the effect of massaging and promoting calf exercise;
